An article on content management systems at Imagining Magazine includes this interesting paragraph,
Erik Josowitz, vice president of corporate strategy for Vignette (www.vignette.com), Austin, TX, grants that free or low-cost software might be fine for departmental use and simple sites. However, he warns, “they have no support model, no upgrade model and no long-term roadmap. When a CIO looks for a content management system, they look for long-term technical support and scalability across an enterprise.”
Of course not a few Vignette customers have had a habit of complaining that even after spending big bucks StoryServer had no support model as well (aside from throwing more money at Vignette).
